These folks live in a realm of fantasy that almost feels real to them. In fact, they switch back and forth between their fantasy thoughts and their very real life soo often, it can mess them up when they start to prefer the fantasy.
The best way to anchor this habit is to infuse themselves with a healthy spirituality that allows for both dreams and reality. The imagination of this placement is a true gift, provided they don’t use it to escape life instead of just making it more interesting.
Oddly enough, the 6th house is the house of a workaholic, therefore it is probably a blessing that the house is in Pisces, as this is the house of one who takes work far too seriously and might just need the balance Pisces offers to “lighten” them up a bit. Just don’t overdo it!
Indulge in play but, don’t forget that it’s a release from life..not a reality in and of itself.
Keep in mind however, that being connected to your spirituality might sometimes bring about a need to trust without proof that feels like only fantasy but is, in fact, more to do with intuition. Fantasy is ignoring the truth, spiritual truth is knowing something but, not understanding how you know it, even if it feels like just a dream.
